Cryo-EM structure of the β-1,3-glucan synthase FKS1-Rho1 complex [PDF]

Nature Communications
β-1,3 Glucan synthase (GS) is essential for fungal cell wall biosynthesis. The GS holoenzyme comprises the glycosyltransferase FKS1 and its regulatory factor Rho1, a small GTPase.

A benchmark dataset for validating FKS1 mutations in Candida auris [PDF]

Microbiology Spectrum
Echinocandins are the recommended antifungal therapy for Candida auris infections in many countries. While echinocandin resistance remains uncommon, recent reports demonstrate an increase in such cases, with the potential for echinocandin-resistant C ...

Hotspot gene conversion between FKS1 and FKS2 in echinocandin resistant Candida glabrata serial isolates [PDF]

npj Antimicrobials and Resistance
Candida glabrata (Nakaseomyces glabratus) is the most common cause of drug-resistant candidemia and is associated with a high mortality rate. Only a few mechanisms of drug resistance are known in C.

Evaluation of a Novel FKS1 R1354H Mutation Associated with Caspofungin Resistance in Candida auris Using the CRISPR-Cas9 System

Journal of Fungi, 2023
Outbreaks of invasive infections, with high mortality rates, caused by multidrug-resistant Candida auris have been reported worldwide. Although hotspot mutations in FKS1 are an established cause of echinocandin resistance, the actual contribution of ...

Structural-guided identification of two modulators of β−1,3-glucan synthase FKS1 [PDF]

Nature Communications
FKS1 is a β−1,3-glucan synthase critical for fungal cell wall formation and a target for antifungal drugs such as echinocandin and ibrexafungerp. However, the mechanisms regulating FKS1 activity remain largely unknown.

FKS1 Is Required for Cryptococcus neoformans Fitness In Vivo: Application of Copper-Regulated Gene Expression to Mouse Models of Cryptococcosis

mSphere, 2022
There is an urgent need for new antifungals to treat cryptococcal meningoencephalitis, a leading cause of mortality in people living with HIV/AIDS. An important aspect of antifungal drug development is the validation of targets to determine whether they ...
